This invention relates to a revolving disk plow, the general object ofthe invention being to provide means whereby the plow will plow a wideswath of ground on each trip across a field, with the parts so arrangedthat the disks can be operated from a small motor.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Fig. 1 is a top plan view of the invention with parts broken away.

Fig. 2 is an elevation of the apparatus.

Fig. 3 is a fragmentary section taken on the line 3--3 of Fig. 2.

Fig. 4 is a top plan view of the plow assembly.

Fig. 5 is a fragmentary vertical sectional View of the two track memberswith a roller of one plow beam engaging the high part of the trackassembly.

Fig. 6 is a similar view showing the roller at the low part of thetrack.

Fig. '7 is a view of the two track members looking, towards the rearpart thereof.

Fig. 8 is a top plan view of the lower member.

Fig. 9 is a bottom plan view of the upper member.

In these drawings, the numeral I indicates a horizontal frame which hasthe depending parts 2 at its rear'end which carry the ground wheels 3and the centrally arranged depending part i at its front end whichcarries the caster wheel 5, said front end of the frame being providedwith the usual clevis 6. Braces 'I extend from the frame intermediatethe ends thereof and the upper track member 8 is sup-ported by thesebraces, the

braces holding the track member in a horizontal position. A lower trackmember 9 is spaced from but parallels the upper track member, both trackmembers being of circular shape and a shaft II] has its lower endconnected to the tubular central portion II of the lower track member,the shaft passing upwardly through a yoke I2 carried by the frame withits upper end connected with the yoke by the nut I3 and a shoulderformed on the shaft engages the lower end of a bushing I4 depending fromthe yoke. As will be seen, this shaft I3 supports the lower track member9. The upper member 8 is provided with 8. depending flange 8' and thelower member 9 is provided with an upstanding flange 9', these flangesbeing spaced apart and the flange 8' of the upper member 8 has adepending part 8" at its rear formed with flaring ends while immediatelyunder this depending part 8", the flange 9' of the lower member 9 isformed with a recess 9" provided with flaring ends. These flanges formcam tracks for a purpose to be hereinafter described. A hollowVertically arranged shaft I5 surrounds the major portion of the shaftIii and is provided with the anti-friction bearings I6 between itselfand the shaft Ill and the lower end of this shaft I5 is enlarged as at Hwith the enlargement being provided with the notches I8, the enlargedlower end of the shaft I5 extending through the centrally arrangedopening I9 in the upper track member 8. A plurality of radiating beamsor shafts have their inner ends pivoted to the arms of a hub 2| which islocated in the enlargement I I of the shaft I5 and the arms pass throughthe notches I8 in the enlarged part of the shaft I5 so that when theshaft I5 is rotated, the shafts 20 with the hub 2I will be revolved. Theshafts are arranged between the upper and lower track members and carrythe rollers 22 adjacent their outer ends which engage the cam edges ofthe flanges of the two track members. The other ends of the beams orshafts 2!! curve downwardly and have the disks 23 attached to theirextremities.

A pulley 24 is attached to the upper end of the shaft I5 and a belt 25engages the pulley and passes over a pulley 26 on the crank shaft 21 ofa motor M. Thus the shaft I5 is driven from the motor. However, I wishit to be understood that any suitable means can be used for driving theshaft l5 from a motor.

Thus it will be seen that the beams or shaft 20 with the disks 23 arerevolved when the shaft I5 is rotated and the cam edges of the trackmembers will cause the disks to enter the ground as the disks passaround the rear portions of the track members and will pass from theground and rise above the same as the disks pass around the side andfront portions of the track members. Thus, the disks will plow a wideswath of ground as the apparatus moves over a field with the plowsforming comparatively short arcuateshaped furrows and as the disks onlyenter the ground as they travel over a small portion of thecircumference of the track members, the device can be driven by acomparatively small motor as all the discs are not in the ground at thesame time as in gang plows as now constructed.

A shield 30 is supported in rear of the patlf'of the disks by a bracket3| for preventing the dirt turned up by the plows from spreading out toofar rearwardly.

With the parts arranged as shown in the drawings, the beam and diskassembly can be moved to a position where all the disks will be engagingthe high parts of the track members so that none. of the disks will bein the ground and thus the apparatus can be moved from one field toanother though if desired suitable means can be provided for raising theentire assembly to position the plows well above the ground so that thedevice can be readily passed through a field and along roads.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily'apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

I claim:

1. A plow of the class described comprising a Wheel-supported frame, anupper track member supported in horizontal position upon the frame, alower track member supported from the frame and parallel with the firsttrack member, said members forming a cam slot between them, the rearportion of which is lower than the rest or the slot with the ends of thelower portion sloping upwardly and outwardly to the rest or the slot,radiating plow beams passing through the slot and having their outerends curving downwardly, plows connected to said outer ends, a roller oneach beam engaging the walls of the cam slot, a hub member to which theinner ends of the beams are pivoted for movement about horizontal axes,and means for rotating the hub member.

2. A plow of the class described comprising a wheel-supported frame,braces depending therefrom, an upper track member held in horizontalposition by the lower ends of the brace members and having a dependingflange having a depending part at its rear, said track member being ofcircular shape, a lower track member of circular shape parallel to theframe and having an upstanding flange spaced from the flange of thefirst member, the flange of the second member having a recess in itsrear part, the two flanges forming a cam slot, radiating shafts or beamslocated between the two track members and passing through the slot,rollers on the shafts or beams engaging the walls of the slot, the outerends of the beams being curved downwardly, disks connected to said ends,a hub to which the inner ends of the beams are connected for pivotalmovement about horizontal axes, means for rotating the hub member and ashield supported from the frame in rear of the path of the disk plows.

FELIX EDGAR HERRING.
